To all whom it may concern Be it known that I, lILLIAM N. SPRINGER, acitizen of the United States, residing at Peoria, in the county ofPeoria and State of Illinois, have invented certain new and usefulImprovements in llows, of which the following is a specification,reference being had therein to the accompanying drawing.

rIhis invention relates to improvements in gang plows. Flows of thischaracter comprise a main or gang frame and a series of individual plowscoupled to the rear side of the frame, thelatter being adapted to behitched to an engine or other suitable tractor.

The object of the invention is to provide a construction suoli that theplows will tend automatically to maintain themselves in proper workingpositions in the ground while passing over ground that is rough, unevenand rocky as well as in the case of soil that is more level and uniform.

Other minor objects and the nature of the invention, in detail, will beunderstood from the following description in connection with thedrawings.

Figure 1 is a side elevation of a plow embodying my improvements,showing the means for attaching it to the draft-frame of a steam gangplow. Fig. 2 is a top plan view of the same. Fig. 3 is a centralvertical section on the line b, o of Fig. 2.. Fig. 4 is a side elevationshowing the beam and its immediate attachments in relatively elevatedpositions. Figs. 5 to 8, inclusive, show details or parts detached.

In the drawings, a plow body is shown having the mold-board'l, a shareat 2, and a land side 3. These parts may be of any usual or preferredsort. rlhey are attached to a beam having the upward extending part orstandard 4 and the horizontal, forward extending, part 5. To the frontend of the beam there are attached the supporting end guiding devices.l6, 6 are standards or bars slidably mounted in guides on the forwardpart of the beam and extending down far enough to provide supports forthe wheels 7 7 which run upon the surface yof the ground. 'Ihe upwardlyprojecting parts 8 of these standards are adjustably connected to thelever 9, which is pivoted at 10 to arm 11, extending upward from thebeam. By means .of the lever theV beam can be adjusted up or downalongVthe standards 6. A toothed segment at 12 and a detent or dog at 13constitute the devices by which the lever 9 can be locked in anyposition of adjustment. When the beam is lowered in relation to thewheels and fastened in a relatively low position, the plow is caused totend to enter more deeply into the ground. Vice versa, when the lever isadjusted so as to lift the beam relatively to the wheels '7,Y the plowis caused to tend to travel upward.

The beam is firmly braced against lateral displacement by the'followingdevices: 14 is a guide having a curved web or plate 15, and a pivotbearing Vat 16, it being supported in the draft bars at 17. With thisguide there is combined a movable guidepiece 18, secured to the forwardend of the beam. It has two plates 19 lying one on one side and theother on the other side of the web of the guide r14. The up and downplay of the beam in relation to the guide 14 is limited by theprojections 20 carried by the guide-piece 18, on the beam, and the stops21, 22, at the upper end and the lower end, respectively, of the guide14.

Connection with the mai-n or gang frame is made as follows: 23 is acoupler piece secured by a pivot pin 24 to the main frame 24a so thatsaid coupler piece is free to swing vertically about the pivot 24. Thecoupler piece has an upright tubular part which receives a pin or bolt25 that serves to pivotally connect to the coupler piece the stirrup 26.27, 28 are adjustable rose plates secured to the stirrup 26. To theplate or disk 28 are secured the draft bars 29, these at their forwardends being connected together preferably by a loop or stirrup 30 whichis fastened to the roseplate 28. The draft-bars 29 extend backward andare pivotally connected at 31, to the beam 'directly above the plowbottom. The connecting devices are the brackets 32 secured to the beam,one upon one side and the other upon the other. These brackets havetubular bearings 33, and the draft bars 29 are fastened by the pivotdevice 31 passing through the bars and through the tubular bearings. 33.

The mode of operation of devices such as described will be readilyunderstood. The draft being applied to the plow beam at a point to therear of the gage wheels 7, 7 and well above the plow body, it will beseen swing laterally,

that reaction of the soil on the plow body tends always to swing theplow body rearward about the draft; connection, with the ward. In otherwords, the plow beam may' be considered a lever having its Vfulcrum at.

l31 with the plow body mounted onV one arm of the lever and the gagewheel on the other, the force being applied, as stated, to the plow.body so as to swing the latterrearward and the gage wheel downward.Thus, if a boulder is encountered', the gage 'wheels 7 in riding up overthe boulder, swing the point of the plow upward as indicated iii Fig. 4'so as to clear the boulder, and as soon as the plow body encounters thesoil' after passing the boulder, the backward drag tends to swing thefront end of? the beam downward so that the pointv of the plow takesinto` the soil promptly and restores' the parts quickly to normalvworkingposition. ground which i's'un'even because of depres sions, itwill be seen that the constant downf ward pressure on the frontendofthebeam will cause the gage wheels to closely follow the surface ofthe'giound in passing such depressions so thatthe' soil at these pointsis plowed to the desired depth. Itv will be seen .that these verticalswinging movements of the plow body and plow beamarepossible by reasonofthe fact that the front end of the beam can freely rise' and fall,within the limits provided by the guidedevices lll and` 18, relative tothe Apivotal connection at 2.4

with the main frame. In addition to the swinging movement of the plowabout. the connection at 31., it will, of course, be understood thatltheA plow is permitted to rise and fallfbodily as the draft bars swingabout the pivotal connection. 2.4 with the main frame. At thesame time,the plow Vas an entirety, including the draft barsis freeto and thiswithoutinterfering with any of the movements of. thevplow in verticalplanes. embodiedv in the draft frame structure provides a simple andeffective means forv winging theeindividual plows.V j
